It really looked like a typical lap under caution at Daytona, until it wasn't. Brett Bodine was at Daytona driving the blue Chevrolet SS pace car last night at the 2014 NASCAR Sprint Unlimited race. He was out there leading the pack when he unexpectedly sped off to the infield, his trunk visibly on fire. As he floored it to safety, you could see the car's passenger cabin fill with smoke. Here's how it looked:

Bodine and his passenger bailed out safely as fire crews raced in and extinguished the flames. So, what caused the fire? It was the battery pack for the pace car's safety lighting system. Slugger Labbe, crew chief for the #27 car, saw it himself and chimed in via Twitter:

I am happy to report that the @TeamChevy pacecar had a battery pack in the trunk for the external safety lights and that is what caught fire
